Abstract:
The human Aurora kinase-A (AK-A) is an essential mitotic regulator that is frequently overexpressed in several cancers. The recent development of several novel AK-A inhibitors has been driven by the well-established association of this target with cancer development and progression. However, resistance and cross-reactivity with similar kinases demands an improvement in our understanding of key molecular interactions between the Aurora kinase-A substrate binding pocket and potential inhibitors. Here, we describe the implementation of state-of-the-art virtual screening techniques to discover a novel set of Aurora kinase-A ligands that are predicted to strongly bind not only to the wild type protein, but also to the T217D mutation that exhibits resistance to existing inhibitors. Furthermore, a subset of these computationally screened ligands was shown to be more selective toward the mutant variant over the wild type protein. The description of these selective subsets of ligands provides a unique pharmacological tool for the design of new drug regimens aimed at overcoming both kinase cross-reactivity and drug resistance associated with the Aurora kinase-A T217D mutation.
Insights
Novel computational methods identified new Aurora kinase-A (AK-A) ligands. These ligands target cancer-driving mutations, overcoming drug resistance and improving inhibitor selectivity for better cancer therapies.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- Aurora kinase-A (AK-A) is crucial for cell division and often overexpressed in cancers.
- Existing AK-A inhibitors face challenges with drug resistance and cross-reactivity.
- Understanding AK-A's interaction with inhibitors is vital for developing effective cancer drugs.
Purpose of the Study:
- To discover novel AK-A ligands using virtual screening.
- To identify ligands that bind to both wild-type AK-A and the T217D resistant mutation.
- To find ligands with improved selectivity for the mutant AK-A variant.
Main Methods:
- State-of-the-art virtual screening techniques were employed.
- Computational screening identified potential AK-A ligands.
- Ligand binding and selectivity were computationally assessed against wild-type and mutant AK-A.
Main Results:
- A novel set of AK-A ligands was discovered through virtual screening.
- Predicted ligands show strong binding to both wild-type and T217D mutant AK-A.
- A subset of ligands demonstrated enhanced selectivity for the T217D mutant over wild-type AK-A.
Conclusions:
- The identified ligands serve as valuable tools for drug development.
- These ligands can help overcome AK-A T217D mutation-associated drug resistance.
- The findings facilitate the design of new cancer treatment regimens with improved specificity and efficacy.
